Ruby

Blocks are ubiquitous in Ruby world. There's as many blocks in every Ruby code as methods - if not even more. It would be very nice to treat blocks as first class citizens like methods and reduce the undesirable begin-end boilerplate inside blocks for exception handling. Here's the syntax proposal:

arr.each do |e| do_something(e) rescue MyException => e # handle exception end 

Just like in methods:

def method do_something rescue MyException => ex # handle exception end 

Currently begin-end block is required for handling exceptions inside blocks:

arr.each do |e| begin do_something(e) rescue MyException => ex # handle exception end end 

Whether the same syntax would apply for {} block/lambda syntax is debatable. {} are typically one-liners and I barely ever saw a begin-rescue-end inside them.
